<h1>HOLE CIRCLE UTILITY</h1>
<p>This program creates a gcode file that can be loaded into linuxnc to run a hole circle operation.</p>

    <button class = 'ui'>VALIDATE INPUTS</button>
    <ul>
    <li>no blank entries.</li>
    <li>spindle speed greater than 0</li>
    <li>circle radius greater than 0</li>
    <li>first hole angle less than 360</li>
    <li>Z travel height greater than 0</li>
    <li>hole start height greater than 0</li>
    <li>drill feedrate greater than 0</li>
    </ul>

    <button class = 'ui'>SAVE AS PROGRAM</button>
    <ul>
    <li>checks for valid input fields</li>
    <li>if MM button is checked, the gcode program will contain a G21 MDI command, otherwise a G20 command</li>
    <li>if a red X remains in the display, the program will not be created</li>
    <li>if a program is successfully created, it can be saved to a user selectable location</li>
    </ul>

    <button class = 'ui'>SEND AS MACRO</button>
    <ul>
    <li>a successfully created program can be transferred to the gcode viewer</li>
    <li>the program is then ready to be run in linuxcnc</li>
    </ul>

<p>The machine should be X and Y zeroed at the center of the desired hole circle.</p>
<p>The Z zero should be set to the top of the workpiece.</p>
<p>The diagram on the right side shows a preview of the hole positions to be drilled.</p>

<div class="admonition">
<p>NOTE: It is up to the user to ensure that all entered parameters are compatible with the machine settings that the program will run on.</p>
